  • The intakes fed thirty-seven-foot-diameter tunnels, which were to be lined with steel water pipes known as penstocks.


  • A hydroelectric power generator combines several main components: a reservoir to store water, an intake system with control gates and intake pipes called penstocks, turbines driven by the high-energy water flow, electricity generators driven by the turbines, transformers to convert the power output to higher voltage, and an outflow system, or tailrace, to discharge the water.

    The Nature of Technology

  • As a result, penstocks, transformers, and power distribution facilities were targeted at Suiho and the other hydroelectric sites, instead of the dams themselves.

    Between War and Peace

  • Following them were the same number of lumbering Skyraiders, who dumped their 5,000-pound bomb loads on the penstocks, transformers, and power distribution facilities around the dam.

    Between War and Peace

  • The enormous penstocks, which were to carry water from the intakes erected in the reservoir to the power-generating turbines, were products of a vast foundry established on Nevada flatland a mile from the river, manned by eight hundred laborers employed by Babcock & Wilcox Co., an Ohio-based maker of steel pressure boilers.


  • The penstocks were fabricated in sections, each comprising three twenty-three-ton steel flat plates twelve feet wide, thirty-seven and a half feet long and two and three-quarters inches thick.


  • Over the following three years, a period in which underground work shifted from the main tunnels to the spillway tunnels and subterranean penstocks that were to carry water from the reservoir to the power turbines, thirty-seven more working men died of pneumonia or coronary problems.


  • Seventeen adits were being driven into the canyon walls to funnel water from the penstocks into the turbines of the powerhouse, a U-shaped structure under construction at the foot of the dam.


  • However, the surplus can often be secured only by building very expensive dams, flumes, penstocks, and other works in addition to turbines and generators.
